Each time you restart the Unity Remote app you must restart Unity or the app will not pick it up. If I am in for a long dev session I plug in device and run remote and then begin work. Means I dont have to keep restarting Unity.

I hope this helps everyone who has a problem with Unity Remote on Android.

First I found that "Unity Remote" is actually an app on the Google Play Store. But still no luck. I believe my drivers and firewall are all fine but no way to test. Is it working with the without Unity Android license?

It seemed that the drivers where not correctly installed even though the Google Drivers were marked as working. It would be nice to have every version of Unity being able to check if the phone USB is correctly setup. Something like a red/green light or whatever.

After that, I didn't have to restart Unity which is really good and the Android displays the game screen.

It's not always the best idea to install google's USB drivers. for some phones only the manufacturer's drivers will enable the use of USB debugging. If you want it to work for your phone, just search for "setting up ADB on DEVICENAME" and you will probably find what you need to do. If ADB see's your device, it should work in Unity.

a simple check is to run "adb.exe" that comes in platform-tools in the sdk from command line as "adb devices" if you see something listed, then you are good to go (in theory).

The extra trick for me was step 4.2, no other tutorials mention going into Project Settings and selecting None to Any Android Device. Restarting Unity and having the Unity Remote app open before was the trick for me.

Anyway this driver will only work for Samsung devices but if you're having the same problems with your own device and Unity Remote, go to your Device Manager on Windows and make sure in the other devices branch (when your device is connected) there are no yellow "!" indicating problems with the drivers you currently have installed, if so then try find your device manufacturers official drivers and hopefully this will solve your problem.

I was fed up with this problem for 6 hours or so and then i found the following solution :-

BlueStacks (android emulating software) interferes with Unity's ability to communicate with a cable connected android device. So even if bluestacks is just installed on your system and not even running, it will interfere with Unity's remote app and it won't be able to run on your physical device connected via a cable. This is valid for android but I dont know about iOS because i don't use it.

Solution - Open windows task manager and kill all tasks with the name "BS" or "Bluestacks" written on them. Then connect your device with Unity remote and follow the normal procedure as mentioned in all threads and tutorials. It shall work like a charm.

This might not be valid for everyone who's unity remote is not working but I thought I'd just share my personal experience so it could help someone out.

Thank you so much Mr. Stark your solution solve my problem! I've been looking around the internet since yesterday because my Unity remote 5 does not connect in my editor. And I finally found the answer from you!
